@Gaw CEO talking to Zen Miners:

It would be great if you could ask them to ship working units and have a real support website and not just an email.  I can't get the stupid things to work.  I have 3 of them.  None of them will register online.  When I plug them into the TV with HDMI it just stupidly asks for the raspberry pi login.  This leads me to believe there is no actual custom software on the memory cards, or if there is it's not loaded. I don't know the login or have any help...has anyone figured it out yet? 

Thanks
